Since April, the number of new infections in a single day has reached a new high, and many square cabin hospitals have been opened. Why can't people with COVID-19 stay home? On the afternoon of April 10, Liang Wannian, head of the expert group of the National Health Commission's Leading Group for COVID-19 Response and Handling, and executive vice president of the Vanke School of Public Health and Wellness of Tsinghua University, gave an explanation in a collective interview with the media in Shanghai.

Liang Wannian said that first, the Omiljung strain spreads rapidly, if asymptomatic infected and mildly ill patients are isolated at home, it may cause recurrent infections to the family, resulting in widespread transmission, "dynamic zero" time extension, short time can not reach the goal of social clearance; second, from the perspective of the global epidemic situation, scientific research shows that asymptomatic infected and mildly ill patients are also infectious; third, home isolation requires conditions, to ensure that families have the corresponding isolation conditions, while monitoring the development of the course of the infected, If vulnerable people such as the elderly are isolated at home, the development of their condition may not be able to be monitored and detected in time, nor can they be treated in time.
In addition, Liang Wannian stressed that the Omiljung strain is mainly transmitted through the respiratory tract, and many studies at home and abroad have also shown that it can also be transmitted through direct contact. If asymptomatic infected and mildly ill patients are isolated at home, there is always a risk of transmission in facilities such as sewers and ventilation systems. Shanghai has a large population density, there are many towers, urban villages, some families share toilets, shared kitchens, and there are many floating populations, assuming that there are asymptomatic infected and mildly ill patients, through contact, it will form a rapid spread, forming a situation that cannot be prevented. Centralized isolation is necessary to protect the health and safety of the people, so it is still necessary in the current situation. (Lu Yang)
